  1. Primary HTN
    • *No specific cause
    • *Combination of genetic and environmental factors.
    • *Obesity, ETOH, smoking, NA intake, alterations inĀ  Renin-Angiotensin system.
  2. Secondary HTN
    • From another cause.
    • Chronic Kidney disease
    • Coarctation of the aorta
    • Cushing's syndrome
    • Drug induced
    • Pheochromocytoma
    • Renovascular HTN
    • Sleep apnea
    • Thyroid disease
  3. Medications that increase BP
    Oral contraceptives, steroids, appetite suppressants, antidepressants (tricylic), Effexor, NSAIDS, some nasal decongestants, and herbal products.
  4. Age of onset:
    20-40
  5. Most common in what race?
    African-Americans
  6. Men or women more?
    Males
  7. What percentage of pts have essential(idiopathic) HTN?
    95%
  8. Strongly associated with what disease?
    Type II Diabetes.
  9. Cardiac output=
    HR, stroke volume, blood volume, and venous capacitance.
  10. TPR (total peripheral resistance) depends on?
    arterioles
  11. BP=
    • CO x TPR
    • (highest during systole)
    • (lowest during diastole)
  12. Pulse pressure=
    systolic-diastolic pressure
  13. Beta receptors do what?
    stimulate the release of Norepinephrine, where as alpha- 2 receptors inhibit norepinephrine release, which produces vasodilation and decreases BP.
  14. Alph-1 receptors-
    Cause vasoconstriction
  15. Beta-2 receptors-
    Cause vasodilation.
  16. Beta-1 receptors-
    • (located on heart and kidneys)
    • -Regulate HR and contractility which affects cardiac output.
